本系列 (LEARNER’S SERIES) 是為升大一的同學編寫。著重於基本概念、基本理論、基本方法等方面的介紹和闡述。引導同學勤於思考，學會提出問題，學會對命題的是非作出正確的判斷。培養同學抽象思考能力，邏輯思維能力。從而提高學生分析問題，解決問題能力。

Complex Numbers 複數(圖書書描述以英語為準)：

本卷提供了複數系統的獨立描述，特別強調了其代數技術，幾何解釋和應用。這一系列的特點是，每個主題都從對主題的分析處理開始，通過指定數學系統的特性來分配其成長所需的條件，然後通過分解成基礎來分析系統。它構成的屬性。

Complex Numbers:

This volume provides a self-contained description of the complex number system that particularly emphasizes its algebraic technique, geometric interpretations and applications.

The special feature of this series is that each topic begins with an analytical treatment of the subject-matter by assigning the conditions necessary for its growth, by inferring the properties of a mathematical system and then analyzing the system by means of the resolution into the fundamental properties of which it is constituted.
